WIRE-LAYING TOOL.

Specification of Letters Patent.

Patented Jan. 1.5, 191%.

Application filed. February 10, 1917. Serial No. 147,894.

To all whom it may concern:

Be it known that I, ltonnnr H. CISSNA, a citizen of the United States, residing at Chicago, in the county of Cook and btate of lllinois, have invented new and useful Improvements in Wire-Laying Tools, of which the following is a specification.

This invention relates to tools used by electrotypers for laying a copper wire around the case to obtain a deposit of uni.- form thickness.

It is the object of the invention to provide a novel and improved tool of the kind stated which is easy to operate, and by means of which the Wire can be rapidly laid.

Other-objects and advantages of the invention will be pointed out in the detailed description appearing hereinafter, and in order that the invention may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing,

Figure l is a plan View of the tool showing how it is used;

Fig. 2 is a side elevation of the tool, partly in section, and

Fig. 3 is a cross section on the line 3-3 of Fig. 1.

Referring specifically to the drawing, 5 denotes a suitable handle carrying at its forward end two projecting shanks 6 and 7, respectively, which are spaced apart and slightly diverge in the direction of their outer ends. The shank 6 is longer than the shank 7 and terminates a short distance in advance thereof.

The outer end of the shank 6 carries an upstanding bracket 8 secured thereto by a bolt or other suitable fastening 9. This bracket supports a reel 10 on which the supply of wire 11 is coiled.

In the shank 6 is a guide eye '12 for the wire 11, and a similar eye 13 is made in the shank 7 close to the outer end thereof. The wire extends downward from the reel 10 to the eye 12, and after passing through the latter, it is threaded through the eye 13. When the tool is in use, the shank 6 is above the shank 7, and the free end of the wire extends from the eye in the latter.

At the forward extremity of the shank 6 is a blade 14: extending transversely of the latter and presented downward.

Figs. 1 and 2 illustrate the manner in which the tool is used. The plate shown at 15 is prepared in the customary manner well known to those skilled in the electrotypers art. At the top of the plate is mounted a copper block 16 to which the cathode terminal of the electric current conductor is connected. The deposit of copper starts at the top of the plate downward, so that the finished electrotype is thicker here. In order that the plate may receive a uniform deposit, a line copper wire is embedded in the surface of the wax case to surround the impression or mold, and located in proximity to the outline of the plating, the ends of the wire being connected to the block 16. The tool hereinbefore described is designed to lay this copper wire, the latter being pressed into the wax case and remaining there. The tool is held so that the shank 7 is at the bottom, as shown in Fig. 2, and it is then carried toward the operator along the border of the wax case, whereupon the wire 11 is drawn off the reel 10 and laid in the wax, the forward end of the shank 7 moving along the surface thereof. The tool is so held that the shank 7 exerts suflicient downward pressure on the wire at the laying point to firmly embed the wire in the wax. After the wire has been laid it is severed by the blade 14 toward which it is drawn and severed by a slight tap. Fig. 1 shows the position of the tool at the commencement of the laying operation, it being drawn in the direction of the arrow. lieferring to Fig. 2, it will be noted that the shank 7 is beveled at the laying point so that this portion may seat squarely on. the surface along which it is drawn.

The tool is rapid in operation, and no extra work is required in pressing the wire down into the wax and the wire can be laid equally well on a case of any temperature. The laying point is in plain view so that the wire is always in sight as it is being laid. The tool lays toward the operator, .and need not be held exactly level for an accurate job. The wire may also be laid in bearers between impressions in view of the narrow laying point of the shank 7, and it can be laid toward the operator or to the right or the left. The wire can be easily cut off without disturbing the laid wire. The wire cannot back up and become tangled over the outside of the reel. The laying point is entirely devoid of obstructions so as not to interfere with the laying operation. The tool has no complicated parts and it is easy to thread. The position of the handle is low so that a firm and direct pressure can be placed on the laying point.

I claim 1. A wire-laying tool comprising a handle, a pair of spaced shanks extending forward from the handle, and provided with eyes for the passage of the wire, the eye of one of the shanks being close to the outer end thereof, and a wire-holding reel carried by the other shank.

2. A. wire-laying tool comprising a handle, a pair of spaced shanks extending forward from the handle, one of the shanks having aneye for the passage of the wire, and said eye being close to the outer end of the shank, said shank end forming a laying point for the Wire, and a wire severing blade on the other shank adjacent to the laying point.

3. A wire-laying tool comprising a handle, a pair of spaced shanks extending forward from the vhandle, and provided with eyes for the passage of the wire, the eye of one of the shanks being close to the outer end thereof, and a wire-holding reel carried by the other shank at its outer end, said end being located in advance of the first-mentioned shank. V

4:. A wire-laying tool comprising a handle, a pair of spaced shanks extending forward from the handle, one of the shanks ha -ting an eye for the passage ofthe wire, and said eye being close to the outer'end of the shank, said shank lend forming a laying point for the wire, and a wire severing blade on the other shank adjacent to and in advance of the laying point. 7

5. A wire-laying tool comprising a handle, a laying shank extending from the handle and having a wire-holding eye adjacent to its extremity, and a wire-severing blade carried by the handle adjacent to the laying point of the shank.

In testimony whereof Iaffix my signature.
